How to create a New User in the Tax Authority Portal

You can create a user with restricted permissions in just three steps. In this guide, you will see step by step how to do it. As a result of creating the user, you will receive a digital number for the new user. This digital number and the password you set for the new user can be shared with FIZ to connect to the Tax Authority and start issuing invoices.

If you do not have access to the Portal das Finanças, refer to ACCESS TO THE PORTAL DAS FINANÇAS – AUTHENTICATION AND PASSWORDS.

1. Click this link (https://www.acesso.gov.pt/gestaoDeUtilizadores/criarForm) to start creating a new user. You will first be asked to log in — use any method you prefer:

• СС / CMD - Citizen Card, Digital Mobile Key

• NIF - your NIF and password

• EORI - EORI ID and password

2. Fill in the fields on the page
​

• Name: Enter a name, such as “FIZ,” to help identify the user and its purpose.

• Password and Confirm Password: Choose a password that is easy to remember, such as your phone number followed by an uppercase letter, a lowercase letter, and a special character (e.g., an exclamation mark).

• Allow Phone and Email Access: These options are optional and can be ignored.

3. On the same page, further down the list, select the authorized operations/permissions. At the end of the list, you will find the required permissions. If you don’t see them on the page, use the → arrow or select “Linhas por página = 50”.
